New study reveals why the Greenfield vs. Brownfield debate is the #1 planning mistake in modern data migrations.
MUNICH, June 10, 2026 /PRNewswire/ -- The biggest risk in a large data transformation isn't choosing the wrong starting point: it's choosing a path which can't be changed. Deciding between a greenfield or brownfield approach feels like a strategic milestone. In reality and proved in the recent Natuvion Transformation Study 2026, conducted by the data transformation specialist Natuvion and NTT Data Business Solutions, it is often the first mistake in planning a migration. All too often, it is assumed that transformations can be planned perfectly from day one. In reality, they rarely are. The uncomfortable truth is that plans are very likely to change during the migration process. According to the 2026 Transformation Study 71 percent of companies change their migration approach mid-project.
